Looking for a Buick Nailhead Engine Nov 26, 2014 11:42:34 GMT -6 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by Hemi-Collector on Nov 26, 2014 11:42:34 GMT -6 I'm searching for a late 50's to mid 60's Buick Nailhead engine. I'd like to find a 401 / 425ci out of a '65 or '66 Wildcat but will look at any.
